Definitions

  • the present invention relates to a ball valve avoiding the problem of the noise due to passage of the fluid through the ball, above all in the intermediate opening positions of the valve.
  • a regulation ball valve for a fluid flow has been devised in which a ball is rotatable to bring a passage thereof from a limit position of full opening of the valve to a limit position of full closure of the valve and vice versa, wherein in said passage there is the presence of perforated baffles that at least at an intermediate position between the limit positions are passed through by the fluid flow, the perforated baffles comprising two perforated metal sheets between which a layer permeable to the fluid is disposed.
  • FIG. 1 is a top view in longitudinal section of a valve in accordance with the invention
  • FIG. 2 represents a detail to an enlarged scale of the valve in FIG. 1 .
  • Valve 10 for fluids (in particular gases) applying the principles of the invention and generally denoted at 10 .
  • Valve 10 comprises a body 11 provided with coaxial inlet 12 and outlet 13 pipe fittings and with an on-off ball 14 that is sealingly rotatable around an axis 15 to bring a passage 16 thereof from a position (of full opening of the valve) in which the passage is aligned with the inlet and outlet ducts, to a position (of full closure of the valve) in which the passage is disposed transversely of the inlet and outlet ducts.
  • the valve is shown with the ball in an intermediate position between the limit positions.
  • baffles or plates 17 disposed inclined to the passage axis.
  • the baffles are each formed of two perforated metal sheets 18 , 19 between which a layer 20 permeable to the fluid is placed.
  • the layer has such a structure that it enables passage of the fluid through a great plurality of also tortuous passages. In particular, the layer is yielding and sandwiched between the plates.
  • the material of layer 20 will be such selected as to be suitable for the type of fluid running through the valve.
  • the layer is made up of filaments, in particular chaotically-disposed metallic filaments, having a structure similar to that of steel wool.
  • the opposite ends of the baffles are closed and appear from opposite openings of passage 16 .
  • the free ends of the baffles are such disposed as to face the inlet and outlet pipe fittings of the valve, so that at least the greatest majority of the fluid flow passes through passage 16 lightly touching the outer surface of the baffles and moving in parallel between one baffle and the other instead of crossing them.
  • the flow is forced to pass through said baffles.
  • the above description of an embodiment applying the innovative principles of the present invention is given by way of example only and therefore must not be considered as a limitation of the scope of the patent rights herein claimed.
  • the conformation of the perforated metal sheets forming the “sandwich”, the number and shape of the holes, the thickness and the porous material can vary depending on use and also different can be the characteristics of the generally “porous” or permeable material that is interposed between the metal sheets to help energy dissipation and break the noise down.
